Hello everyone! I encountered frequent lags and loss of smoothness in KDE Plasma on Wayland (slightly better on X11, but the problem remains) when using two monitors on a system with an NVIDIA 3070 Ti. Information about the system: OS: Arch Linux x86_64 Kernel: Linux 6.11.5-arch1-1 Uptime: 3 ho…

I have the same issue. In my case, turning off GSP helped, but didn’t really solve the problem. My setup: Kubuntu 24.10 / Plasma 6.1 / Wayland / Kernel 6.11.0-13-generic / Intel 13800H / RTX4060 Mobile. To debug this, I have used the following tools: Compositor Desktop effects: show FPS nvtop: m…

(This is with GSP off) In my experience, when the card is in P8 mode (RTX 4070), KDE tends to stutter. Doing anything that makes the performance mode increase, makes KDE smooth again as long as it doesn’t go down to P8 mode again. In my opinion a desktop shouldn’t lag with a RTX 4070 just because …

Can confirm this is happening also on GNOME. X11 is very smooth, but on Wayland there is sometimes some loss of smoothness. Recording one of the displays with OBS “solves” the problem and it’s smooth all the time. I saw this happening on driver 565, but it’s still happening on driver 570. My card i…

Hi, I have a similar issue but on a Lenovo Legion laptop with external dual-monitors setup, with Nvidia RTX 4060, on X11. My issues are with certain apps: Android Studio/IntelliJ, Steam and when games are starting up through wine/proton. Didn’t tried native linux games because I don’t own any. Fro…

Update: Somehow the Android Studio issue is no longer present even in version 550 (550.144.03), on KDE Neon. Forgot to mention, previously that the issues where on KDE Neon. The Steam and games part is still the same, but since it’s just the startup part, it doesn’t bother me. My previous setup w…

I have had lots of intermittent stuttering problems as well, and I found the following (several overlapping issues): different DEs don’t handle full-screen applications the same, particularly in multi-monitor setups. Even disabling compositing on full-screen windows doesn’t work reliably. With c…

Ok, was running some more tests on new driver version 570.124.04 released today. The issue seems mostly fixed. During normal desktop usage, animations and scrolling feel overall smoother and basically on par with X11. However, the lag/loss of smoothness can still happen if I leave my computer for a…

Since my last reply, I’ve been using nvidia’s proprietary package for the most part, with GSP disabled using the “options nvidia NVreg_EnableGpuFirmware=0”. The same driver version is currently installed - 570.124.04. Now I have removed this parameter and checked the smoothness without it. Indeed, …

I switched to the open gpu driver, it’s much better now than it ever was. But I still notice a difference when the card is in P8 perf mode compared to for example P2. It’s buttery smooth in P2 mode. But that difference is also noticeable with proprietary driver and GSP off.

I have the same issue on my Lenovo LOQ 15ARP9 with a RTX 4060 Mobile… It’s very annoying. Doing the OBS Screen Recording trick removes 95% of the lags/frame drops in the DE(tested with KDE and GNOME), but sometimes it still lags, also my card is always on P8 and when I start the recording it puts i…

Kwin maybe, since almost all things in kwin_wayland happen in the main thread. I reported performance issues here and here.
